How do I create a ListView with rounded corners in Android

Question

User · Answer

Yet another solution to selection highlight problems with first, and last items in the list:

Add padding to the top and bottom of your list background equal to or greater than the radius. This ensures the selection highlighting doesn't overlap with your corner curves.

This is the easiest solution when you need non-transparent selection highlighting.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@color/listbg" />
    <stroke
        android:width="2dip"
        android:color="#D5D5D5" />
    <corners android:radius="10dip" />

    <!-- Make sure bottom and top padding match corner radius -->
    <padding
        android:bottom="10dip"
        android:left="2dip"
        android:right="2dip"
        android:top="10dip" />
</shape>

Although that did work  it took out the entire background colour as well  I was looking for a way to do just the border and just replace that XML layout code with this one and I was good to go    lt shape xmlns android  http   schemas android com apk res android  gt       lt stroke android width  4dp  android color   FF00FF00    gt       lt padding android left  7dp  android top  7dp              android right  7dp  android bottom  7dp    gt       lt corners android radius  4dp    gt   lt  shape gt

This was incredibly handy to me  I would like to suggest another workaround to perfectly highlight the rounded corners if you are using your own CustomAdapter   Defining XML Files  First of all  go inside your drawable folder and create 4 different shapes    shape top      lt gradient     android startColor   ffffff      android endColor   ffffff      android angle  270   gt   lt corners     android topLeftRadius  10dp      android topRightRadius  10dp   gt      shape normal      lt gradient     android startColor   ffffff      android endColor   ffffff      android angle  270   gt   lt corners     android topLeftRadius  10dp      android topRightRadius  10dp   gt      shape bottom     lt gradient     android startColor   ffffff      android endColor   ffffff      android angle  270   gt   lt corners     android bottomRightRadius  10dp      android bottomRightRadius  10dp   gt      shape rounded     lt gradient     android startColor   ffffff      android endColor   ffffff      android angle  270   gt   lt corners     android topLeftRadius  10dp      android topRightRadius  10dp      android bottomRightRadius  10dp      android bottomRightRadius  10dp   gt        Now  create a different row layout for each shape  i e  for shape top     You can also do this programatically changing the background       lt TextView     android id    id textView1      android layout width  wrap content      android layout height  wrap content      android layout gravity  center      android layout marginLeft  20dp      android layout marginRight  10dp      android fontFamily  sans-serif-light      android text  TextView      android textSize  22dp    gt    lt TextView     android id    id txtValue1      android layout width  match parent      android layout height  48dp      android textSize  22dp      android layout gravity  right center      android gravity  center right      android layout marginLeft  20dp      android layout marginRight  35dp      android text  Fix      android scaleType  fitEnd    gt       And define a selector for each shaped-list  i e  for shape top    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt  -- Selected Item -- gt        lt item android state selected  true          android drawable   drawable shape top    gt       lt item android state activated  true          android drawable   drawable shape top    gt        lt  -- Default Item -- gt       lt item android state selected  false          android drawable   android color transparent    gt   lt  selector gt    Change your CustomAdapter  Finally  define the layout options inside your CustomAdapter   if position  0     convertView   mInflater inflate R layout list layout top  null     else    convertView   mInflater inflate R layout list layout normal  null      if position  getCount  -1    convertView   mInflater inflate R layout list layout bottom  null      if getCount    1    convertView   mInflater inflate R layout list layout unique  null       And that s done

actually  i think the best solution is described on this link   http   blog synyx de 2011 11 android-listview-with-rounded-corners   in short  it uses a different background for the top  middle and bottom items  so that the top and bottom ones would be rounded

Update   The solution these days is to use a CardView with support for rounded corners built in     Original answer   Another way I found was to mask out your layout by drawing an image over the top of the layout  It might help you  Check out Android XML rounded clipped corners

User · Answer

to make border u have to make another xml file with property of solid and corners in the drawable folder and calls it in background

I m using a custom view that I layout on top of the other ones and that just draws the 4 small corners in the same color as the background  This works whatever the view contents are and does not allocate much memory    public class RoundedCornersView extends View       private float mRadius      private int mColor   Color WHITE      private Paint mPaint      private Path mPath       public RoundedCornersView Context context            super context           init               public RoundedCornersView Context context  AttributeSet attrs            super context  attrs           init             TypedArray a   context getTheme   obtainStyledAttributes                  attrs                  R styleable RoundedCornersView                  0  0            try               setRadius a getDimension R styleable RoundedCornersView radius  0                setColor a getColor R styleable RoundedCornersView cornersColor  Color WHITE              finally               a recycle                         private void init             setColor mColor           setRadius mRadius              private void setColor int color            mColor   color          mPaint   new Paint            mPaint setColor mColor           mPaint setStyle Paint Style FILL           mPaint setAntiAlias true            invalidate               private void setRadius float radius            mRadius   radius          RectF r   new RectF 0  0  2   mRadius  2   mRadius           mPath   new Path            mPath moveTo 0 0           mPath lineTo 0  mRadius           mPath arcTo r  180  90           mPath lineTo 0 0           invalidate                Override     protected void onDraw Canvas canvas               Paint paint   new Paint            paint setColor Color RED           canvas drawRect 0  0  mRadius  mRadius  paint              int w   getWidth            int h   getHeight            canvas drawPath mPath  mPaint           canvas save            canvas translate w  0           canvas rotate 90           canvas drawPath mPath  mPaint           canvas restore            canvas save            canvas translate w  h           canvas rotate 180           canvas drawPath mPath  mPaint           canvas restore            canvas translate 0  h           canvas rotate 270           canvas drawPath mPath  mPaint

Here is one way of doing it  Thanks to Android Documentation though     Add the following into a file  say customshape xml  and then place it in  res drawable customshape xml    lt  xml version  1 0  encoding  UTF-8   gt    lt shape xmlns android  http   schemas android com apk res android        android shape  rectangle  gt         lt gradient           android startColor   SomeGradientBeginColor           android endColor   SomeGradientEndColor            android angle  270   gt         lt corners           android bottomRightRadius  7dp            android bottomLeftRadius  7dp            android topLeftRadius  7dp            android topRightRadius  7dp   gt    lt  shape gt     Once you are done with creating this file  just set the background in one of the following ways   Through Code  listView setBackgroundResource R drawable customshape    Through XML  just add the following attribute to the container  ex  LinearLayout or to any fields    android background   drawable customshape    Hope someone finds it useful

The other answers are very useful  thanks to the authors    But I could not see how to customise the rectangle when highlighting an item upon selection rather than disabling the highlighting  alvins  bharat dojeha   The following works for me to create a rounded list view item container with no outline and a lighter grey when selected of the same shape   Your xml needs to contain a selector such as e g    in res drawable customshape xml     lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android   gt   lt item android state pressed  true   gt       lt shape xmlns android  http   schemas android com apk res android   gt           lt stroke android width  8dp  android color   android color transparent    gt           lt padding android left  14dp  android top  14dp                  android right  14dp  android bottom  14dp    gt           lt corners android radius  10dp    gt           lt gradient               android startColor   android color background light               android endColor   android color transparent                android angle  225   gt        lt  shape gt   lt  item gt   lt item android state pressed  false  gt       lt shape xmlns android  http   schemas android com apk res android   gt           lt stroke android width  8dp  android color   android color transparent    gt           lt padding android left  14dp  android top  14dp                  android right  14dp  android bottom  14dp    gt           lt corners android radius  10dp    gt           lt gradient               android startColor   android color darker gray               android endColor   android color transparent                android angle  225   gt        lt  shape gt           lt  item gt      Then you need to implement a list adapter and override the getView method to set the custom selector as background       Override     public View getView int position  View convertView  ViewGroup parent              snip         convertView setBackgroundResource R drawable customshape             snip         and need to also  hide  the default selector rectangle e g in onCreate  I also hide my thin grey divider line between the items    listView setSelector android R color transparent   listview setDivider null     This approach solves a general solution for drawables  not just ListViewItem with various selection states

There are different ways to achieve it  The latest approach is using CardView for each ListItem component  Here are some steps   Create a layout resource file  let s name it  quot listitem xml Copy and paste the under enclosed Listitem xml layout body into it  Create RowItem class for each listitem data  later you will instantiate this to assign values for each list item  Check Code below  RowItem class  Create a custom ListAdapter  let s name it ListAdapter class  and inflate this   1  list item layout for each list item  Check the second code snippet for this one  Set this adapter   3  the way you set default adapters inside an activity the listview belongs to  maybe the only difference would be you first have to instantiate RowItem class with values and add RowItem object to your adapter then notify your adapter that the data is changed     listitem xml    lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt       lt LinearLayout         xmlns android  quot http

kris-van-bael  For those having issues with selection highlight for the top and bottom row where the background rectangle shows up on selection you need to set the selector for your listview to transparent color   listView setSelector R color transparent     In color xml just add the following -   lt color name  transparent  gt  00000000 lt  color gt
